Wolffia plant named ‘MANKAI’

ABSTRACT

A new and distinct Wolffia Globosa plant that exhibits fast vegetative propagation, an ovoid shape, and is neutral in taste.

Botanical classification: Wolffia Globosa.

Varietal denomination: ‘MANKAI’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct Wolffia Globosavariety known by the varietal name ‘MANKAI’. ‘MANKAI’ was derived froman unnamed and unpatented Wolffia globosa variety originating from RamatHa'Golan, Israel that was placed in a cultivated area of a controlledwater growth medium having a pH range between 4-11 and water temperaturerange between 17-30° C., with continuous low movement, aeration, andfertilization being provided in Moshav Merhavia, Israel. After a periodof a forced selection process and observation, ‘MANKAI’ was discoveredand selected in said cultivated area as an improved Wolffia globosavariety by the inventor in 2005. When compared to an unnamed andunpatented Wolffia Globosa variety known to the breeder, ‘MANKAI’exhibits a similar vegetative propagation rate, but the unnamed varietyhas a round shape, differs in length, and is light green in color. Thenew variety has been trialed and tested and has been found to retain itsdistinctive characteristics and remain true to type through successivepropagations.

The parental plant and ‘Mankai’ are similar in vegetative propagationrates, however ‘Mankai’ differs from its parent plant in that the parentplant is round and 0.5 mm-1 mm in length, whereas ‘Mankai’ is ovoid and0.4 mm-0.85 mm in length. In addition, the parental type is lightergreen in color compared to ‘Mankai’.

The following characteristics distinguish the new variety from otherWolffia Globosa varieties known to the breeder:

-   -   1. Ovoid shape;    -   2. Length of 0.4-0.85 mm and width of 0.3-0.65 mm;    -   3. Fast vegetative propagation—8 to 9 times over a period of 16        to 19 days before dying as a white frond devoid of any further        daughter fronds within it;    -   4. Neutral taste;    -   5. Dry biomass of 4-5%; and    -   6. Green (7490C) color.

DESCRIPTION OF THE DRAWINGS

The accompanying photographic drawings illustrate the new cultivar, withthe color being as nearly true as is possible with color illustrationsof this type:

FIG. 1 illustrates a population of plants of the new variety in logphase. The image was photographed with a Micros Cam 500 attached to astereoscopic binocular microscope (Ladybird MZ1240) with lighting fromabove and below. The level of objective magnification is 45×;

FIG. 2 illustrates a non-synchronous population of plants in mid-logphase. 30 of 36 fronds are at some stage of budding, from incipientemergence of a daughter frond to almost complete separation of a motherand daughter frond. The size ranges of budding mother fronds are 0.6-0.8mm in length and 0.5-0.6 mm in width. The variation in size is due tothe growth cycle of a mother frond, which typically births 8-9 daughterfronds in its life time: a first-time mother reaches 0.6 mm in length, athird to eighth time mother reaches 0.8 mm in length. The widths areproportionate to the lengths. The image was photographed with a NikonSMZ 1500 stereo microscope with lighting from above.

FIG. 3 illustrates a single mature plant of the new variety.

FIG. 4 illustrates a close up, dorsal view of a budding plant of the newvariety with the dorsal face floating at the water line. The motherfrond is birthing a daughter frond, with the meristematic pouchdecorated with characteristic concentric lines of elongated cells at themouth of the pouch. The image was photographed with a Nikon SMZ18stereoscopic binocular microscope using a Nikon DS-RI1 camera withlighting from above. The magnification was provided by the 0.5 mm bar.The length of the mature mother frond is 0.8 mm and the width is 0.55 mm

FIG. 5 illustrates a close up, side view of a budding plant of a motherfrond of the new variety that reveals the green, photosynthetic, almostflat, dorsal face at the surface of the water and thediminishingly-green submerged body. The emerging daughter frond appearsgreen throughout. The image was photographed with a Nikon SMZ18stereoscopic binocular microscope using a Nikon DS-RI1 camera withlighting from above. The magnification was provided by the 0.5 mm bar.The length of the mature mother frond is 0.8 mm and the depth (height)is 0.7 mm.

FIG. 6 illustrates a population of plants of the new variety, with oneplant shown in side view. The image was photographed with a Micros Cam500 attached to a stereoscopic binocular microscope Ladybird MZ1240 withlighting from above and below. The level of objective magnification is45×.

FIG. 6a illustrates a new frond appearing from a mother frond of the newvariety. The image was photographed with a Micros Cam 500 attached to alight microscope (Bresser Art. No. 57-23100). The level of objectivemagnification is 10×.

FIG. 7 illustrates a mother frond with a daughter frond of the newvariety. The image was photographed with a Micros Cam 500 attached to alight microscope (Bresser Art. No. 57-23100). The level of objectivemagnification is 10×.

FIG. 8 illustrates a new frond of the present variety. The image wasphotographed with a Micros Cam 500 attached to a light microscope(Bresser Art. No. 57-23100). The level of objective magnification is10×.

FIG. 9 illustrates young fronds of the new variety. The image wasphotographed with a Micros Cam 500 attached to a light microscope(Bresser Art. No. 57-23100). The level of objective magnification is 4×.

FIG. 9a illustrates an open pouch of the new variety. The image wasphotographed with a Micros Cam 500 attached to a light microscope(Bresser Art. No. 57-23100). The level of objective magnification is10×.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the characteristics of thenew variety. The data which defines these characteristics are the resultof asexual reproductions first carried out by budding in 2005 in MoshavMerhavia, Israel. The new variety was grown in a water medium at roomtemperatures under continuous low movement, with aeration, andfertilization provided. If the electrical conductivity was measuredhigher than 1.8 mS, the culture medium was refreshed. The location wherethe variety was described at an age of log stage growth was in MoshavDekel, Israel under cool LED lighting with an intensity of 160 μE m−2s−1. Color references are primarily from the Pantone Catalogue—The PlusSeries 2016.
